Each
drive on a control expansion or expansion enclosure has two light-emitting diode (LED) indicators;
they have no controls or connectors.
The drive indicator LEDs on all systems use the same color and flashing patterns for both sizes
of drives.
This table shows the location of the LEDs on a small form factor (SFF) 2.5-inch drive. SFF drives are supported on control enclosures and expansion
enclosures.

Expansion enclosures also support large form factor (LFF) drives. Storwize® V7000 Gen2 and Storwize V7000 Gen2+ control
enclosures do not support LFF drives.Figure 2 shows the
location of the LEDs on a 3.5-inch drive.Figure 2. LED indicators on a horizontal 3.5 in. (8.89 cm) drive
This table lists the status descriptions for the two LEDs on each type of drive.
